[Gmsh] Questions about gmsh

[DILASSER Guillaume]

Dear Li Yang,

Gmsh is unitless. It is up to you to build your geometry, mesh and physical model using a consistent unit system.

Sincerely Yours,

Guillaume Dilasser

import geometries from other CAD software in standard exchange formats. Gmsh uses OpenCASCADE to import such files, including label and color information from STEP and IGES files;

Can I edit STEP/IGES/BRep models?

Yes: with the OpenCASCADE kernel (SetFactory("OpenCASCADE");), load the file (Merge "file.step"; or ShapeFromFile("file.step");) and add the relevant scripting commands after that to delete parts, create new parts or apply boolean operators. See e.g. demos/boolean/import.geo.
